Diffusive Electronic Transport in Superconductor-Semiconductor-superconductor Junctions of Al or Nb on Δ-Doped GaAs
Czechoslovak Journal of Physics/Czechoslovak journal of physics(1996)
Abstract
We report measurements on planar superconductor-semiconductor-superconductor (S−Sm−S) junctions consisting of a n++ modulation doped conduction layer in MBE grown GaAs with superconducting contacts of Al or Nb. At distances between the two superconducting banks below ≈3.5μm we observe a coupling between the two superconductors, due to multiple Andreev reflections at the S−Sm interfaces.
